摘　　要：介绍了一种应用于C波段接收机射频前端,并利用耦合微带线设计的射频滤波器。利用ADS软件的仿真结果验证了所设计的射频滤波器具有如下特性：中心频率为C1；80MHz通带内信号起伏较小；噪声系数约1.8dB；能有效抑制镜像信号干扰,满足设计要求。An RF fitter, which is applied to C-band receiver RF front and designed with the coupling microstrip line, is introduced. The following performance of the desinged filter is verified by the simulation results obtained with the software ADS2001 ：the center frequency of C1 ,the flat passband response in desired bandwidth of 80MHz, the low noise figure of 1.8dB, and enough rejection at the image frequency, comisting with the demand of the design.
